5m Waterproof DS18B20 Shielded Temperature Sensor

This 5 m long waterproof temperature sensor contains a digital DS18B20 with 1-Wire communication in a metal probe. The shielded cable makes the connection less susceptible to interference. The chip is factory calibrated. One digital input is enough to read it, and several sensors can share the same input. A 4.7 kΩ resistor between VCC and Data is required for operation, and only one even with several sensors on the same input.

Recommended Accessories:

• Resistance Set 600 pcs. Assorted 1/4W 1% Accuracy
• Shelly Plus AddOn

Features:

• Digital temperature sensor DS18B20 with 1-Wire interface
• Cable with braided shield and 3 wires
• Each sensor has its own serial number, so several can share one input
• 4.7 kΩ pull-up required, the internal pull-ups of the Arduino are not sufficient
• Arduino libraries «DallasTemperature» and «OneWire» in the Library Manager

Application Examples:

• Temperature measurement in liquids and outdoors
• Several measuring points on one input
• Connection to a Shelly Plus AddOn
